LAMP-PROTECTOR.

Specification of Letters Patent.

Patented June 18, 1907.

Application filed December 14, 1903. Serial No. 185,020.

-To all whom it may concern.-

Be it known that I, GEORGE A. RUssELL, a citizen of the United States,residing at Worcester, in the county of Worcester and State ofMassachusetts, have invented a new and useful Lamp-Protector, of whichthe following is a specification.

This invention relates to that class of lamp protectors or guards whichare adapted to be secured-upon the bulbs of incandescent electric lamps.

The especial object of this invention is to provide a protector or guardcomprising a wire frame-work with a single set of spring fingers forsupporting the guard in place upon the bulb. The spring fingers in theconstruction herein illustrated are connected to the closed end of thewire frame-work and extend toward the open end of the wire frame-work,so that they may be spread apart to receive the globe or bulb of anelectric lamp when the protector is to be put in place thereon.

In the accompanying drawing, Figure 1 is a side view of an electric lampprotector or guard constructed according to this invention, and Fig. 2is a view of an electric lamp bulb showing the engagement of the springfingers therewith.

In the use of that class of guards or lamp protectors to which thisinvention relates it has been a matter of difliculty to provide aconstruction which is adapted for use on a variety of diiferent sizesand shapes of electric lamps. In an electric lamp protector constructedaccording to this invention, I employ a set of spring fingers which willcenter the guard or support upon the lamp bulb and which aresufliciently flexible to adapt themselves to a variety of shapes oflamps.

In a previous application for patent filed by me Nov. 9, 1903, SerialNo. 180,294, I have shown and claimed a lamp guard in which two sets ofspring fingers extend from the open end of the wire frame-work back intothe body thereof. In this construction one set of spring fingers engagesnear the end of a lamp-globe and the other set of spring fingers engagesthe contracted or neck portion of the lamp-globe. In'a lamp guardconstructed according to this invention, I employ a single set of springfingers which extend in the opposite direction; that is to washer orcenter-ring 12.

say, in this construction, Iemploy a set of spring fingers which aresecured in the frame-work so that the free ends of the spring fingersextend toward the open end of the wire frame-work.

Referring to the drawings and in detail, a lampguard constructedaccording to this invention, as herein illustrated, comprises an endring 10. Extending from the ring 10 are frame wires 11 which areconnected to a At different points the frame-Wires 10 may be connectedby spreading rings. In the present construction, one spreading ring 13is located sub stantially at the bend of the frame-wires 11, from whichthe ends of the wires are bent in to the center-ring 12, and two rings14 and 15 are located close together and are secured in S-shaped bendsof the frame-wires 10. The spring fingers which serve to hold the guardupon an electric lamp or bulb are soldered in place in the end-ring 12,or are otherwise secured so that their free ends are presented oppositethe open end of the wire frame-. work. By means of this construction asingle set of spring fingers will hold the framework in place upon thelamp. These fingers may be com aratively long and will be suiiicientlyfiexi le to receive lamps of different shapes and to take up the jar ofobjects which might otherwise break the electric lam a Tiie lampguardsor protectors constructed according to this invention are put intoplaceby simply forcing the same onto electric lamps, and on this account,constructions of this kind can be much more readily put on and taken offthan with the prior forms of construction in which the protectingframework is provided with a hinged section. In

addition to this by dispensing with the hinged hat I do claim and desireto secure by Letters Patent of the United States is 1. As an article ofmanufacture, a lamp guard comprising a frame-work having an open end anda substantially closed end and centering fingers for holding an electriclampglobe centrally in the frame, said centering fingers consisting ofpieces of wire, each of which is fastened at one end to said closed endof the frame-work, and the rest of which is unattached, whereby thefingers can be sprung apart to receive the lamp.

2. As an article of manufacture, an electric lamp protector or guardcomprising a wire frame-work consisting of a ring, an end- Washer,frame-wires connecting the ring and end washer, with spreading rings forholding the frame wires in place, and spring fingers secured to the endwasher with their free ends extending toward the open end of thewire-frame.

In testimony whereof I have hereunto set my hand, in the presence of twosubscribing witnesses.
